Large public events sometimes led
to the creation of unique Underground maps designs. This maps was published
by London Transport to guide the crowds of well-wishers visiting London for the
coronation of King George VI in 1937. The map focus on Central London and the areas
closed to traffic surrounding the Coronation Procession route. King George’s
route is divided into six coloured sections with advice for well-wishers about
the best bus lines and Underground stations to use to attend each section.

Bus routes are marked with red lines, Green Line coach routes (buses carrying passengers from the outer suburbs and countryside) are in green. Entry and crossing points for pedestrians are noted along the procession route, and the roads which remained open for guests attending the Coronation at Westminster Abbey are also specifically marked. Quite how many attendees to the actual coronation ceremony at Westminster Abbey might have used this map is unclear, but it is a nice addition, nonetheless.

A very similar map was issued in 1953 for Queen Elizabeth II's coronation – a change to the decorative
border, a slightly different procession route, and the addition of a seventh coloured section for Queen Elizabeth's route are the only major changes. Bus routes are marked in a much more
prominent red colour on the 1953 maps, likely due to the growing
importance of bus travel by the 1950s.
